Abstract 
A new enantiornithine bird, Bohaiornis guoi, gen. et sp. 
nov., is described in this paper. The holotype, 
presumably a sub-adult, is a complete, fully articulated 
skeleton from the Lower Cretaceous Yixian Formation of 
western Liaoning, northeastern China. Bohaiornis exhibits 
some similarity in morphology to Eoenantiornis, but 
Bohaiornis is much larger than Eoenantiornis and differs 
from all previously known enantiornithine birds including 
Eoenantiornis in having the following features: caudal 
end of the articular pointed caudoventrally, sacral 
centra strongly compressed transversely, and clavicular 
ramus straight with a laterally expanded omal end. The 
almost perfectly preserved skeleton of this new specimen 
not only reveals many morphological features previously 
unknown in basal birds, but also clarifies many fine 
details of previously known features.
